For a transistor amplifier, the collecor load resistance `R_(L) = 2k` ohm and the input resistance `R_(i) = 1k `ohm . If the current gain is 50, calculate voltage gain of the amplifier.

Explanation

`R_(L) = 2k Omega = 2 xx10^(3) Omega `
`R_(i) = 1 kOmega = 1 xx 10^(3) Omega`
`beta = 50 `
Voltage gain `(A_(V)) =beta xx ( R_(L))/(R_(i)) =( 50 xx 2 xx 10^(3))/( 1 xx 10^(3))`
`A _(V ) = 100 `
